# Labels

You can add labels to deployment groups and targets with the `labels` property, which accepts a single label or a list of labels. Deployment groups and targets inherit labels from the deployment group they belong to and can have labels of their own but can't remove the inherited labels.

You can use labels to choose which deployment targets to include in commands. For example, you can deploy only those targets that have a **dev** label.

#### Example

Let's add label **app** to targets **dev-environment** and **prod-environment**, and another label **others** to **infra** and **sandbox** targets. We could use these labels to deploy all application targets (targets with the **app** label).

{% code title="deployment/targets.yml" %}

```yaml
vars:
  cost-center: 12345
  budget: 2000

targetsSchema: budget

deploymentGroups:
  all:
    configSets: security
  all/shared:
    targets:

        labels: others

    targets:

        labels: app
      - name: sandbox
        accountId: "111133335555"
        labels: others 
  all/application/prod:
    targets:
      - name: prod-environment
        accountId: "333355557777"
        labels: app
```
